I'm using int data type for one of my columns but for 99.99...% its data never
would be &gt; 65K, Should i change it to smallint (It would save some Gigabytes
disks in a few months) or Cassandra Compression would take care of it in
storage?

What about blob data type ? Isn't better to use it in such cases? could i
alter column type from smallInt to int in future if needed?
